Usage
See the example Xcode project. It contains 2 targets:
- ProgressRingExample - a simple example containing a single progress ring with adjustable parameters.
- ActivityRingsExample - an advanced usage example replicating Activity app by Apple. It also contains additional classes for convenient grouping of 3 ring progress views together.
Interface Builder
MKRingProgressView can be set up in Interface Builder. To use it, set the custom view class to MKRingProgressView. Most of the control's parameters can be customized in Interface Builder.
Code
let ringProgressView = RingProgressView(frame: CGRect(x: 0, y: 100, width: 100, height: 100))
ringProgressView.startColor = .red
ringProgressView.endColor = .magenta
ringProgressView.ringWidth = 25
ringProgressView.progress = 0.0
view.addSubview(ringProgressView)
The progress value can be animated the same way you would normally animate any property using UIView's block-based animations:
UIView.animate(withDuration: 0.5) {
ringProgressView.progress = 1.0
}
